riflcing any of the advantages of the invention. which is adapted toreceive a lug 25 at the front One of the many possible embodiments ofthe edge of the blade backing member. invention is illustrated in theaccompanying In assembling the elements of the razor, they d aw inwhich: first occupy the positions shown in dotted lines 511 Figure 1 isa front elevation, partly in section, in Fig. 1 of the drawing, in whichthe resilient of a razor constructed in accordance with the guard memberis in its normal flat state. The invention, the elements being shown infull lines rear edge 16 of the said guard member abuts in shavingpositions, and in dotted lines before then against the flange 15 butonly at its ends. the blade is being flexed; Fig. 2 is a central Therear edge of the blade is similarly disposed.

' transverse section taken through the elements, Consequently, the saidguard member and blade would not be properly guided as the blade andguard member are being flexed, as will hereinafter be described,notwithstanding the fact that the lugs 25 on the blade backing memberare disposed in the re-entrant recesses 24 in the blade and in there-entrant recesses 24 in the guard member, the latter recesses being inalignment with the recesses 24 in the blade. However, inasmuch as theguard member and blade are provided each with an oblong hole, into whichthe flattened pin 13 on the blade backing member is fitted, properguiding and blade positioning means are provided. When the handle isturned in the proper direction to flex the blade, it is obvious thatboth the blade and the said guard are flexed longitudinally by reason ofthe fact that the transverse edges of the rigid backing member rest uponthe blade. The blade and guard have a tendency to flex, when the handleis screwed home, so as to assume the shape of the rigid backing member,that is to say to be curved'longitudinally. In the shaving positions ofthe elements, shown in full lines in Fig. 1 of the drawing, both theblade and guard assume the exact shape of the said backing member, andin any'intermediate position the blade assumes the shape of the guard sothat I in all positions the longitudinally curved cutting edge of theblade is fully protected by the guard teeth. Owing to the fact that thecutting edge of the blade, in shaving position, is longitudinallycurved, curved surfaces of the body may be readily shaved, for instancethe arm pits.

As appears from Figs. 4 and 7 of the drawing, the aperture 21 in theblade is placed close to'the rear longitudinal edge of the blade. Acircle which may be circumscribed the aperture 21, shown in dotted linesand indicated by the numeral 26 in Fig. 7 of the drawing, is thuslocated in close proximity of the rear edge of the blade. The purpose ofthis arrangement is as follows: Assuming that some one were to design ablade to fit the razor herein described, the aperture in the blade wouldhave to be circular as shown in dotted lines in Fig. 7 of the drawing inorder to accommodate the pin 13. If such aperture were cut into theblade, it would weaken the latter to such an extent that it would crackadjacent its rear edge when being flexed. Unauthorized blademanufacturers could,

razor construction herein described, provided that the specific locationand configuration of the blade aperture herein described could beprotected by Letters Patent.

As appears from Figs. 1 and 2 of the drawing, the screw-threaded portionof the handle 20 is provided with a laterally extending flange 21, whichbears against the underface of the guard member. The purpose of thisextended surface is to cause the guard member and the blade to flex on alarge radius when the handle is screwed home on the pin 13.

What I claim is:

In combination, a flexible blade, a blade holder comprising a rigidlongitudinally curved back member and a flexible guard, said blade andguard having each an oblong hole therein, a pin on the back memberconforming in shape and size to the holes and adapted to fit in theholes to hold and align the blade and the guard, and means on the pinengaging the guard to hold the blade and the guard against the backmember and cause the blade and guard to bend longitudinally to assumeany form from a straight line to the curvature of the back member.
